I feel proponents of any programming language put a lot of spin around what isolated aspects it is good for, but fail to illustrate what a programmer in even one target domain gains from using it.
Are there programming language implementations unlike what is described above, that you feel back up their marketing?
Dunno. If it fits the purpose and you get a lot of libraries and tooling around your specific domain… Why not make use of it? Python is easy to learn and has a lot of nice stuff for data science. Or R for statistics… Considering the absence of other complete frameworks when doing embedded programming… wouldn’t you just use C++?
You are right Python and C++ have a huge amount of collateral available going for them. But is the utility of their language features backed up by any examples or explanations? Rigid object-orientedness as seen in Python, C++, Java, modern Javascript is not conducive to good software in practice, and we are just muddling along.
Object-oriented is a design pattern that the language can facilitate. Just because a language supports “is a” doesn’t mean “has a” does not exist. There are a lot of design patterns. Use the best language and design patterns for your team.
Neither python or JS are “rigidly” OOP, they have support for them but you can very easily do functional or imperative programming in either. out of those I believe Java is the only one that “rigid OOP” is a fair descriptor for, and I could be wrong on that as its not a language I’ve used (c# which I have and started as essentially microsoft Java has moved away from that style by incorporating numerous functional features from f#)
Fun fact, you can totally do functional programming in C++ too. Actually, it is in the top-right of the λ-cube, making it (in a specific sense) a more functional-programming language than Haskell or LISP :D
